N′-[(E)-2-Fluorobenzylidene]benzohydrazide

Abstract

The asymmetric unit of the title compound, C14H 11FN2O, contains two independent molecules, both of which adopt the E conformation with respect to the azomethine C=N bond. The molecules are non-planar, with dihedral angles of 26.92 (12) and 11.36 (11)° between the benzene and phenyl rings. In the crystal, molecules are linked through N-H⋯O=C and N-H⋯N hydrogen bonds into chains along [101]. C-H⋯O contacts link these chains into layers parallel to (001). The three-dimensional crystal packing is stabilized by π-π interactions, the shortest separation between the centroids of benzene rings being 3.884 (1) Å.
